YieldReaction ConditionsOperation in experiment
51% With tert.-butylnitrite; copper(ll) bromide; In acetonitrile; at 45.0℃; for 3.0h; A slightly yellow solution of 2,5-difluoro-4-(trifluoromethyl)aniline (10.0 ml; 76.708 mmol) in MeCN (90 ml) was treated with copper(ll) bromide (17.133 g; 76.708 mmol), and the green heterogeneous mixture was heated to 45C. A solution of tert-butyl nitrite (10.0 ml; 84.379 mmol) in MeCN (20 ml) was then added dropwise over 30 min., and the resulting mixture was further stirred at 45C for 2h30. The dark-green heterogeneous reaction mixture was allowed to cool to rt, and was directly purified by FC (DCM). After concentration to dryness under reduced pressure, the expected product 1-bromo-2,5-difluoro-4-trifluoromethyl- benzene was obtained as an orange oil (10.290 g; 51 %). LC-MS: tR = 1.07 min.; [M+H]+: no ionisation.
